SPECIFICATION forming part of Letters Patent N o. 723,722, dated March 24, 1 903.

Application filed April l, 1902. Serial No. 100,957. (VNO model.) V

To all whom it may concern;

Be it known that I, WILLIAMH. PARKER, a subject of the King of Great Britain, resid.- ing at Longbranch, in the county of Moumouth and State of New Jersey, have invented a new and Improved Punching-Machine, of which the following is a full, clear, and eXact description.

The invention relates to coin-operated machines for testing physical strength; and its object is to provide a new and improved punching-machine which is simple and durable in construction and arranged to co1'- rectly show .by means of an indicator the force of the blow delivered by the operator on the machine.

The invention consists of novel features and parts and combinations of the same, asl

will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a p art of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure lis a front elevation of the improve ment, parts being shown in section. Fig. 2 is a transverse section of the same. Fig. 3 is an enlarged transverse section of the indicating mechanism. Fig. 4 is a sectional front elevation of the same on the line 4 4- of Fig. 3. Fig. 5 is a sectional plan view of the coinchute, also showing the coin-carrying lever, the section being on the line 5 5 of Fig. 4.

Fig. 6 is an enlarged sectional front elevation of -part of the punching-head, its projection, the coin-carrying lever, and the plate of the gearing for the indicating device. Fig. 7 is an enlarged sectional front elevation of the indicating-tube, the lifter, and the pointer. Fig. 8 is an enlarged sectional plan view of the same on the line 8 v8 of Fig. 3, and Fig. 9 is a similar view of the same on the line 9 f) of Fig. 3. 4

The improved punching-machine is mounted on a suitable stand or casing A, formed at its front with an opening A', through which projects the punching-head B, against which the blow is directed with the fist of the person using the machine. The punching-head B, of any approved construction, is secured on the upper end of a lever C, fulcrumed at or near its middle at C in the lower portion of the casing A,.a'nd a spring D presses the said lever, so as to hold the latter and the punching-head B normally in an outermost position, asplainlyillustrated in Fig. 2. The lower end of the lever C is connected with a dash-pot to give the desired resistance to the lever C and the punching-head B when the latter is struck by the fist of the operator. The dash-pot consists, essentially, of a link E', connecting the lever C with a piston E, mounted to reciprocate in a cylinder E2, secured in the casing A, and in the Wall of the said cylinder, near the rear end thereof, is ar ranged an air-opening E3, and in the rear end of the cylinder is arranged an air-outlet, normally closed by a valve E4, adapted to open upwardly on the return or rearward movement of the piston E. Now when the several parts are'in the position shown in Fig. 2 then the piston E is at the inner end of the cylinder E2 and covers the opening E3, and when a blow is delivered on the punching-head B then the-lever C is forced to swing againstfthe tension of the spring D and against the resistance offered by the piston E, sliding in the cylinder E2. Y

Now it will be seen that on the first impact of the fist on the punching-head B the piston E has to be moved past the opening E3 before air can pass into the rear end of the cylinder. Consequently the rst impact lon the punching-head Bis resisted by full atmospheric pressure against the front face of the piston E. As soon as the piston E passes the opening E3 then air passes into' the rear end of the cylinder, and consequently the piston E moves forward easily, thus reducing the resistance against the inward movement of the punching-head B. As soon as the force of the blow on the punching-head B has ceased the spring D forces the lever C back to its former position, thus moving the punching-head B-back into an outermost position, as shown in Fig. 2. At the same time the piston E moves inward in the Acylinder E2, and as the air in the rear end of thc cylinder can now readily escape through the opening E3 and the outlet-valve E4 it is evident that the spring D can readily accomplish the desired result, as very little resistance is offered to the inward movement of the piston E.

ICO

The forward movement of the punchinghead B is limited by a flange B', formed on the punching-head and abutting against the inner face of the front of the casing, as shown in Fig. 2. On this flange B' of the punchinghead, and preferably at the top thereof, is

' secured a projection F, adapted to engage the portion G' of the coin-carrying lever G, provided at its free end with pins G2 for snpporting a coin passing to the pins through the coin-chute I-I,eXteudingWithin the casing and having an elongated opening H' for the passage of the pins G2. (See Fig. 4.) The upper end of the coin-chu te H is formed with the usual mouth or entrance end H2, extending on the front of the casing to allow Gon- Venient insertion of a coin into the chute. Normally the lever G stands in the position shown iu Fig. 4 by the action of the weighted end G2, so that the`portion G' is out of alinement with the projection F. The lever G is fulcrumed on and mounted to slide on a guide-rod I, which, with the guide-rod I', eX- tends transversely in the casing A and forms a bearing for a plate J, lof-ated immediately in the rear ot' the lever G at the portion G', and formed with an opening J' for the passage of the [.)rojectionF in case the lever Gis held in a normal uppermost posi tion and a blow is given to the punching-head B. Thus when no coin is introduced into the machine the lever G remains in the position shown and described, and when the punching-head B is moved forward, as previously described, then the projection F clears the portion G' of the lever G and passes through the opening J' without disturbing either the lever G or the plate J. When, however, a proper coin is introduced into the chute H, it engages the pins G2, and thus overbalances the weighted end G3 of the lever, so that the latter swings downward in front of the opening J' and the projection F, and when the punching-head B is pushed inward the said projection F engages the portion G', and as the latter is in engagement with the front face of the plate J it is evident that both the lever and the plate are caused to slide transversely. The plate J is secu red to the lower run of a sprocket chain K, extending transversely and passing over sprocket-wheels K' and K2, jonrnaled in the front and rear of the casing A., The upper run of the sprocket-chain K is in mesh with a sprocket-pinion L, secured on a shaft L', jonrnaled in the casing A, and on the said shaft is secured a' larger sprocket-wheel L2, over which passes a sprocket-chain L2, eX- tending upwardlyandpassingoverasprocketwheel L, journaled in the top of the casing A. On one of the runs of the sprocket-chain L3 is secured the arm N' of a lifter N, pert'erably made cone-shaped and normally seated on a correspondiugly-shaped seat O', arranged in the bottom of a guideway O in the form of a tube, extending vertically in the casing A. The arm N' is preferably forked, as plainly shown in Fig. 9, andcarries a transverse pin N2, secured to the lifter N, the said pin eX- tending through slots O2, arranged in the sides of the guideway O. Immediately above the lifter N is arranged a pointer-disk P in the form of a piston, provided on its sides with pointer-arms P', extending through the slots O2 and through a slot A2 in the front of the casing to indicate on a graduation R, arranged on the front face ot' the casing and the sides of the slot, as plainly indicated in Fig. l. A rest P2 is arranged above the seat O' of the guideway O for the pointer-disk to rest on when in a normal lowermost positionthat is, when the pointers P' indicate zero on the graduation R. (See Figs. l and 23.) The pointer-disk P is so arranged that it remains in position within the guideway O by frictional contact ofthe disk with theinner wall of the guideway O. Now when a transverse movement is given to the plate J, as previously explained, then a traveling motion is im parted to the sprocket-chain K t0 rotate the sprocket-wheel L, which in turn rotates the shaft L' and sprocket-wheel L2, so that a traveling motion is given to the sprocket-chain L2. When this takes place, the run of the sprocket.- chain L2, carrying the arm N', moves upward, so that the lifter N is caused to move up in the guideway O and in doing so carries the pointer-disk P in a like direction, so that the pointers P' indicate on the graduation R- that is, as soon as the force of the blow on the head B ceases and the head moves back toits normal outermost position then the arm F' on the projection F engages the rear face of the plate J and pulls the same back to a no1'- mal forward position, thus rotating the st firocket-gearing above described in the opposite direction to return the lifter N'to a normal lowermost position. The pointer-disk P remains in the position in which it was lifted by the lifter N to properlyindicate the force of the blow struck by the operator on the punching-head B until the lifter reaches its lowermost position. When the cone shaped lifter N moves down into its seat O', it spreads the gnideways sufficiently apart for the guideways to release the pointer-disk P, and the latter now drops by its own weight back onto the rest P2. Thus the pointers P' remain stationary fora short time-that is, suiiiciently long to permit of conveniently reading on the graduation R the force of the blow struckon the punching-head B. It is understood that the lever G is moved rearward with the projection F and plate J, and the latter in doing so moves the pins G2 from under the coin held in the chute H, so that the coin drops down through the chute into the casing.

Having thus described my invention, I claim as new and desire to secure .by Letters Patent- 1.
